344991 ÷ 64 
We want to figure out the number of times 344991 can be divided by 64.

Advancing to step 1:
64 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 64

On to step 2:
The number 64 fits into 34 0 times, leaving a remainder of 34.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 34 after subtracting 0 from 34.
Take the next digit (4) from the dividend and append it to 34, then repeat: 344 / 64

Going ahead to step 3:
64 goes into 344 5 times with a remainder of 24.
Put 5 as the next digit of the answer. 
Result so far: 5.0
The remainder is 24 after subtracting 320 from 344.
Append the next digit (9) from the dividend to 24 and continue with: 249 / 64

On to step 4:
249 divided by 64 is 3 with a remainder of 57.
The next digit of our result is 3. 
Result so far: 53.0
Subtracting 192 from 249 leaves us with 57.
Bring next digit (9) of the dividend behind the 57 and repeat the process: 579 / 64

Let's proceed to step 5:
64 goes into 579 9 times with a remainder of 3.
The next digit of our result is 9. 
Result so far: 539.0
If we take 576 away from 579, we end up with 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 64

Advancing to step 6:
The number 64 fits into 31 0 times, leaving a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 5390.0
If we take 0 away from 31, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 7:
When dividing 310 by 64, we get 4 with a remainder of 54.
Put 4 as the next digit of the answer. 
Result so far: 5390.4
If we take 256 away from 310, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 8:
When dividing 540 by 64, we get 8 with a remainder of 28.
Put 8 as the next digit of the answer. 
Result so far: 5390.48
Deduct 512 from 540 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 9:
When dividing 280 by 64, we get 4 with a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 5390.484
Subtracting 256 from 280 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 10:
240 divided by 64 is 3 with a remainder of 48.
Record the quotient 3 as the next digit in the result. 
Result so far: 5390.4843
If we subtract 192 from 240, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 11:
When dividing 480 by 64, we get 7 with a remainder of 32.
Record the quotient 7 as the next digit in the result. 
Result so far: 5390.48437
Subtract 448 from 480 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 12:
320 divided by 64 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 5390.484375
If we subtract 320 from 320, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 13:
If we divide 0 by 64, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 5390.484375
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 14:
The number 64 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 5390.484375
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 5390.484375, and the remainder is 0.0.
